help my cat live longer

So I have this cat named Beauty. I got her when I was like 3 and I am 12 now. That makes her 8 or 9 because I just turned 12. I want to take her to college with me. That means she will have to live to be around 14 years old. I don't know if my math is correct lol. But, I want to keep her healthy and happy so she can keep me company through my days of college. Can you give me any tips?

P.S. She is currently an outside cat. She has been spayed. And she is very healthy.

It's pretty rare that a cat can live that long.
But anything's possible. Ideally, I want my dog to live forever, but I know he won't. Just make sure she eats right, stays away from illnesses, and is quite active (:
